Answer:
Choice B is correct
Step-by-step explanation:
The variable x represents the number of hours;
2, 4, 5, 7, 9
The least value is 2 while the maximum value is 9. The scale to be used must accommodate all these values. The scale can thus begin from 0 to 10. Choice A is incorrect since the values 7 and 9 will not be accommodated in the graph.
The y variable represents the number of pages read;
50, 100, 125, 175, 225
The least value is 50 while the maximum value is 225. The scale to be used must accommodate all these values. The scale can thus begin from 0 to 250. Both choices C and D are incorrect since none of the values will be accommodated in the graph.

Answer:
<h3>B. 9/4</h3>
Step-by-step explanation:
According to the diagram, there are 5 x's in and 8 of negative 1 in the left hand side of the equation. This is represented mathematically as;
= 5x+8(-1)
= 5x - 8 .............. 1
In the right hand side, there are 3 of -x's and 1 in 10 places. This is also expressed as;
= -3x+1(10)
= -3x+10 ............ 2
Equate 1 and 2 and find x
5x-8 = -3x+10
add 7 to both sides
5x-8+8 = -3x+10+8
5x = -3x+18
add 3x from both sides
5x+3x = -3x+18+3x
8x = 18
x = 18/8
x = 9/4
Hence the value of x that makes the equation true is 9/4
